There are various items in the safety and health standards of the manufacturing industry, but they can be divided into work-related diseases and musculoskeletal diseases according to the standards for sickness and accident victims. Musculoskeletal diseases occur frequently in manufacturing and can lead to a decrease in labor productivity and a weakening of competitiveness in manufacturing. In this paper, to detect the musculoskeletal harmful factors of manufacturing workers, we defined the musculoskeletal load work factor analysis, harmful load working postures, and key points matching, and constructed data for Artificial Intelligence(AI) learning. To check the effectiveness of the suggested dataset, AI algorithms such as YOLO, Lite-HRNet, and EfficientNet were used to train and verify. Our experimental results the human detection accuracy is 99%, the key points matching accuracy of the detected person is @AP0.5 88%, and the accuracy of working postures evaluation by integrating the inferred matching positions is LEGS 72.2%, NECT 85.7%, TRUNK 81.9%, UPPERARM 79.8%, and LOWERARM 92.7%, and considered the necessity for research that can prevent deep learning-based musculoskeletal diseases.

Manufacturer's competitiveness in the MRO industry, which is to stimulate the growth of the business-to-business e-commerce market, has recently become more important. A nuclear parts manufacturer was supplying products based on irregular demand from clients which differs from ordinary MRO business practices. The reason for this is the Nuclear Parts Manufacturer has fallen behind the e-commerce performance of other industries, and they lack global competitiveness due to the low efficiency of the individual companies within it. In this study, we developed an MRO based a-Marketplace system to minimize repetitive ordering of raw materials, lack of reusability and inefficiency of transaction processing which was a result of the former legacy business practice, In order to accomplish the purpose of this study, we implemented a web based automated CR system which considered the characteristics of the nuclear parts manufacturing: the system has sub modules such as ordering, product management, transaction management, warehousing and raw material handling. As a consequence of the system implementation, H corporate successfully automated ordering of raw materials, quotation processing and inventory management compared to the legacy business process, achieving increased efficiency by reducing wasteful resources.

Based on the survey, this paper examines entrepreneurs' attitude toward corporate lending in Pusan region. The results show that the relationships of manufacturing firmswith banks are different from those of non-manufacturing firms. These are mainly due to the differences in the operational grounds between them. The non-manufacturing firms have their operational ground in Pusan, thus they have local banks as their mainbanks and depend heavily on mainbanks' credits. However the business network of the local banks is not broad enough to satisfy the manufacturing firms financial service needs. Therefore, the manufacturing firms maintain close relationship with not only regional local banks but also other banks. The results of the study demand the local banks to produce information of the regional firms and to monitor them more widely and tightly. One of the important contributions of this paper is that it has succeeded in making clear the importance of relationship banking of the local banks.

With the advent of the ICT-based 4th industrial revolution, the convergence of the manufacturing industry and ICT seems to be the new breakthrough for achieving the company's competitiveness and play a role on the key element for accelerating the revival of the manufacturing industry. When the smart factory is implemented, each plant can analyze the quantity of data collected, build the data-driven operation systems which can make decisions, and ultimately discover the correlation among many events in the manufacturing sites. As the customers' needs become diversified more and more, it is required for the company to change its operating method from large quantity batch production systems to customizable and flexible manufacturing systems. For performing this requirements, it is essential for the company to adopt the smart factory. Based on technology acceptance model (TAM), this study investigates the factors influencing continuous use intention and switching intention of the smart factory. To do so, a questionnaire survey is conducted both online and offline. 122 samples are used for the study analysis. The results of this study will provide many implications with many researchers and practitioners relevant smart factories.

In order to prepare the fundamental data for the improvement of noisy working environments and the effective hearing conservation program on workers exposed to industrial noise, the authors surveyed the working processes and evaluated the noise levels on 56 manufacturing industries in Pusan area from April to July in 1985. The results were summarized as follows : 1. The noise level was the highest in shipbuilding and repairing(95.6 dBA), and followed by steel rolling(94.0 dBA), manufacture of motor vehicles(93.1 dBA), manufacture of fishing nets(92.9 dBA), manufacture of testiles(92.5 dBA), iron and steel foundries(89.3 dBA), manufacture of metal products(89.1 dBA), preserving and processing of marine foods(87.0 dBA), manufacture of rubber products(85.3 dBA), manufacture of plywood(84.9 dBA) and manufacture of paints(84.5 dBA). 2. Among fifty surveyed working processes, the noise level of twenty-one processes (42%) exceeded the threshold limit value for 8 hours per day. 3. As the allowable exposure times by governmental threshold limit values to industrial noise level(dBA), cocking of shipbuilding and repairing and plating(CGL) of steel rolling were the shortest(30 minutes), and followed by assembling(rivet) of manufacture of motor vehicles(1 hour) weaving of manufacture of textiles and shot, machine, pipe laying of shipbuilding and repairing(2 hours). 4. By the result of octave band analysis on noisy working processes in excess of 90 dBA, the sound level was the highest at 2,000 Hz or 4,000 Hz. 5. It was recognized that the measurement of overall sound pressure level was also effective as octave band analysis in evaluating the industrial noise.

In order to address the crisis of the regional employment structure caused by the recent restructuring of the shipbuilding industry, this study estimates the shipbuilding industry's Employment Linkage Effect(ELE) across regions and industries. Consequently, the study uses the hypothetical extraction method on the shipbuilding industry from the 2013 Regional Input-output Table. The analysis results are as follows. First, the shipbuilding industry's ELE across industries is estimated at its highest in wholesale and retail, followed by shipment, other manufacturing, project supporting service, machine and equipment manufacturing, and metal product manufacturing. These industries either have a high employment to GDP ratio or are directly related to the shipbuilding industry in terms of production activities. Second, the Southeastern Korea's ELE on South Jeolla Province is very low, and, accordingly, South Jeolla Province is isolated in the employment structure of the shipbuilding industry. Therefore, when the government establishes measures to tackle the crisis of employment caused by the shipbuilding industry's restructuring, it should prioritize identifying such regional employment structures, as demonstrated above, and incorporate them into the regional industry policy.

The purpose of this study is to study the effect of internatioanl entrepreneurial orientation of small and medium-sized Chinese manufacturing companies on export performance. A total of 183 corporate data were used for empirical analysis for Chinese manufacturing export companies. In summary, first, international entrepreneurial orientation was shown to have a significant positive effect on export performance, second, international etrprenurial orientation was shown to have a significant positive effect on absorption capacity, and third, the stronger environmental dynamics and network capacity, the stronger international business orientation and export ability. The implications of this study are summarized as follows. It suggests that the more innovative, enterprising and risk-taking Chinese SMEs are, the better their export performance and the better their ability to absorb foreign knowledge. It also suggests that small business managers must continue to strengthen their network capabilities to improve export performance through international entrepreneurial orientation, and this relationship is further strengthened in a dynamic environment. It also suggests that the impact of firm's absorption capacity on export performance will weaken over time.

In this study, the characteristics and oral health status of manufacturing workers were investigated to confirm the factors affecting their risk of developing dental caries and to prepare basic data for developing oral health promotion programs for such workers. A self-administered questionnaire survey and saliva microorganism examinations (S. mutans and Lactobacillus tests) were conducted from July 1 to August 1, 2014 targeting the manufacturing workers in the Busan and Gyungnam areas, to confirm the factors affecting dental caries development among manufacturing workers. As a result, the risk of dental caries was found to be higher in the workers who worked for 10 hours or longer a day than in those who worked for less than 10 hours a day, and in the smokers than in the non-smokers. A 1-point increase in the brushing pattern score resulted in 0.044 times less risk of dental caries development in the S. mutans test and 0.004 times less risk in the Lactobacillus test Therefore, systematic support is needed to improve the work environment of manufacturing workers, along with continuous oral health education in workplaces.
